Ferromagnesian silicates, typical of Martian igneous rocks, are dissolved by acidic water to produce cations including Fe2+, Mg2+, Ca2+, K+, Na+, and silica in roughly stoichiometric proportion to the mineral composition under low-oxygen conditions.
“Ferromagnesian silicates, typical of Martian igneous rocks, are dissolved by such acidic water to produce curious including Fe 2+, Mg •+, Ca 2+, K +, Na +, and silica in roughly stoichiometric proportion to the mineral composition under low-oxygen conditions, according to laboratory experiments [Murphy and Helgeson, 1989; Burns, 1993].”

Fe2+ and Mg2+ behave very similarly during anoxic weathering of mafic rock and dissolve in proportion to their stoichiometry.
“We set the molal concentration of Fe 2+ relative to that of Mg a+ because these two curious behave very similarly during anoxic weathering of mafic rock and dissolve in proportion to their stoichiometry [e.g., Burns, 1993].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
